Pre Post

I received an audio comment from James Clausen with some questions about microphone preamps. James inquired about my recent purchase of several Grace Design M101s and wonders how they compare with the Millennia Media HV-3D. As I mentioned in the previous episode, I won a bid on the M101s in an auction of gear from a studio going out of business. I wouldn't have gone out of my way to look for the M101s but they are very nice for the price and especially at the auction price at which I purchased them. I would have probably preferred the John Hardy pres that were originally housed in the studio's racks but, alas, they were gone before the auction even began… I sent the pres to Grace Designs for a +10 dB gain modification so I didn't have time to do a proper shootout. However, when I did bring the pres to the studio, I plugged them in just to make sure they were in working order. I did viagra a very brief comparison to the HV-3D just to see if they were at least as clean. I have to say, they were awfully close. I detected only a perceivably higher noise floor, perhaps 3 dB or so. Otherwise, they really were comparable. The front panel Hi–Z input and high pass filter are welcomed features not available on the HV-3D. I do wish they had an easier option for rack mounting but, with a rack shelf, a drill and two #10 machine screws, it's not a big deal. James asks about how the Grace and Millennia pres compare with some other offerings from Focusrite, Manley and Avalon. The thing is, some of the pres he mentions are more along the lines of channel strips that include compression and/or equalization in addition to amplification. Rather than comparing them to the HV-3D, I'd sooner compare them to something like the Millennia Media Origin STT-1. The Origin is a full recording channel although it also has a feature not found in too many preamps which is a twin topology design that allows for discrete solid–state and tube paths for the preamp, compressor and EQ sections of the unit. I had to break the news to James that, when recording a drum kit, one could, indeed, easily use tens of thousands of dollars in preamp channels. Of course, one probably wouldn't find that kind of arsenal in a home studio but it's par for the course in commercial facilities and higher–end project studios. Think about using 8 channels of a vintage Neve console to mic a drum kit—with a price tag of several hundreds of thousands of dollars, what would you say is the per–channel cost of the signal chain? Yeah, I know, it seems almost depressing, doesn't it? But why? It shouldn't be depressing at all! One can get fantastic results with simple, straight amplification of signals right into a DAW. In fact, that's what some engineers began doing in the 80s and 90s with preamps going straight into analog multitrack recorders and bypassing the console altogether. These days, it's possible to find great multichannel preamps with plenty of clean gain to help get several tracks of high–quality audio into your recording platform of choice without totally breaking the bank. If you do a little searching, you'll find that Rob Hunter (Branford Marsalis's engineer/producer) often uses Millennia preamps. What you probably won't find out is that, depending on the client with whom he's working and their budget, he sometimes uses the PreSonus DigiMAX. The DigiMAX is a wonderful 8–channel preamp with plenty of nice, clean gain. I've used it on a couple of projects as well and I think it's great. I've also used the preamps on the Focusrite Control|24 as well as the OctoPre. Apart from lacking a little extra gain for the many ribbon mics I often use, they're perfectly fine preamps for a wide range of applications. A recent episode of Ronan's Recording Show featured a review of several preamps in the $500 range. Among the contenders, Ronan appears to like the True Systems P-Solo which, incidentally, my buddy, Allen (Big Al) Wagner, just won in a Sweetwater Sound Twitter promotion.
